The CLEF-IP 2011 collection is composed of multilingual patent documents, including extracts of the MAREC dataset by IRF. It contains patents, physically stored as a collection of XML files en coding patent documents that have partial translations of the patent text between German, English and French (the EPO’s official languages).
This collection contains approximately 3.5 million XML documents, referring to 1.5 million patents, and most of patent documents were published by the European Patent Office (EPO), but that also include certain patents published by the World Intellectual Patent Organization (WIPO).
I have extracted multilingual parallels segments (English-German, English-French, and French-German) from the CLEF-IP 2011 collection. I made the corpus available to the research community.
